The importance of meat, particularly salmon, to body size, population productivity, and conservation of North American brown bears
We hypothesized that the relative availability of meat, indicated by contribution to the diet, would be positively related to body size and population productivity of North American brown, orExpand

Effects of moose movement and habitat use on GPS collar performance
We tested a radiotelemetry collar that uses a Global Positioning System (GPS) unit to calculate animal locations. We placed the collar in a range of cover types and compared locations reported by theExpand

Role of Tannins in Defending Plants Against Ruminants: Reduction in Protein Availability
We tested the hypothesis that tannins defend plants against large herbivores by decreasing protein availability. Digestion trials were conducted with mule deer (Odo- coileus hemionus) and resultsExpand

Role of brown bears (Ursus arctos) in the flow of marine nitrogen into a terrestrial ecosystem
Abstract We quantified the amount, spatial distribution, and importance of salmon (Oncorhynchus spp.)-derived nitrogen (N) by brown bears (Ursus arctos) on the Kenai Peninsula, Alaska. We tested andExpand

Temporal, Spatial, and Environmental Influences on the Demographics of Grizzly Bears in the Greater Yellowstone Ecosystem
Abstract ABSTRACT During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. UnderstandingExpand

Trophic relations of brown and black bears in several western North American Ecosystems
We examined the historical and current diets of brown bears (Ursus arctos) and black bears (U. americanus) in the Greater Yellowstone Ecosystem, Glacier National Park and immediately adjacent areasExpand

Use of sulfur and nitrogen stable isotopes to determine the importance of whitebark pine nuts to Yellowstone grizzly bears
Whitebark pine (Pinus albicaulis) is a masting species that produces relatively large, fat- and protein-rich nuts that are consumed by grizzly bears (Ursus arctos horribilis). Trees produce abundantExpand

Mitochondrial phylogeography of moose (Alces alces): late pleistocene divergence and population expansion.
We examined phylogeographic relationships of moose (Alces alces) worldwide to test the proposed existence of two geographic races and to infer the timing and extent of demographic processesExpand

Effect of seasonal differences in dietary meat intake on changes in body mass and composition in wild and captive brown bears
The influence of seasonal dietary meat intake on changes in body mass and composition in wild and captive brown bears (Ursus arctos) was investigated because the importance and availability of meatExpand
